Behaviorally unresponsive patients may exhibit ERPs indicating some preserved information processing. Behaviorally unresponsive patients may exhibit some degree of semantic processing of spoken sentences. High CRS scores may indicate the presence of ERPs, but low CRS scores do not exclude ERPs. When presenting semantic material to patients, sentences should be preferred over word-pairs. ERPs in DOC patients may be delayed and of reversed polarity adding to the difficulty of interpretation.
